Description

Dialyzer plastic injection box Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a dialyzer glue injection box. Background Art

[0002] The existing hemodialyzer shell and the membrane filaments inside the shell are fixed and sealed by injecting sealant, wherein the sealant needs to be injected using a glue injection box. Currently, the existing glue injection boxes on the market are assembled from an upper cover and a shell, and mechanical locking is used between the two. Due to reasons such as injection molding or improper assembly, there is a gap between the two. When performing high-speed centrifugal glue injection, glue leakage often occurs, resulting in uneven glue volume at both ends of the dialyzer, or glue contamination on the surface of the dialyzer product, requiring additional cleaning, which leads to an increase in the defective rate, reduced production efficiency, and increased production costs.

[0006] Compared with the prior art, in the present invention, since an integrated shell is adopted, glue leakage will not occur, the glue outlet channel can discharge glue evenly, and glue contamination on the product surface can be avoided, thereby improving the product yield.

[0007] Furthermore, the middle of the bottom of the glue-containing cavity is convex upward to form a boss, and the edge of the boss is provided with a plurality of ribs;

[0008] The other end of each convex rib is connected to the inner side wall of the glue containing cavity, and each glue outlet channel is located between two adjacent convex ribs.

[0009] Furthermore, the boss is a conical structure, and the height of the boss is smaller than the depth of the glue-containing cavity and higher than the height of the rib.

[0018] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0019] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0020] Please refer to Figures 1 to 3. A dialyzer glue injection box provided in one embodiment of the present invention includes an integrated shell 10, the top of the integrated shell 10 is concave to form a glue cavity 101, and a plurality of glue outlet channels 102 are provided on the outer wall. One end of each of the glue outlet channels 102 is connected to the glue cavity 101, and the other end is connected to the D-column hole on the dialyzer shell through a glue injection tube 11.

[0021] It should be noted that, in the present application, the one-piece housing 10 is made of an integrated blow molding process, and the material used is polyethylene or polypropylene. Before starting the glue injection, the membrane filaments are first loaded into the dialyzer housing, and then the membrane filaments are preliminarily fixed by setting a baffle at the end of the dialyzer housing. During the high-speed centrifugal glue injection process, the liquid sealant is injected from the top of the glue-containing cavity 101, and then passes through the glue outlet channel 102, the glue injection tube 11 and the D column hole in sequence, and finally thrown into the end of the dialyzer housing under the action of centrifugal force to seal and solidify the membrane filaments and the end of the dialyzer housing.

[0022] Specifically, the present application is provided with four glue outlet channels 102 and four glue injection tubes 11, each glue outlet channel 102 is located at the four corners of the integrated shell 10, and the two relatively arranged glue injection tubes 11 form a group, and a group of glue injection tubes 11 injects glue into the D-column holes at both ends of a dialyzer shell.

[0023] It should be noted that, since the two groups of injection tubes 11 can respectively injection-mold a dialyzer housing 10 at the same time, the injection efficiency can be improved. In order to avoid interference, the two dialyzer housings are staggered, so the two groups of injection tubes 11 need to be set to different lengths.

[0024] Please refer to FIG. 2 and FIG. 3 . Specifically, when the glue injection tube 11 a is a short tube, the glue injection tube 11 a is an L-shaped structure, and a reinforcing block 11 a 1 is provided at the corner to increase the strength of the corner.

[0025] Please refer to Figures 2 and 3. Furthermore, when the glue injection tube 11b is a long tube, the glue injection tube 11b includes a horizontal tube 11b1 connected to the glue outlet channel 102, a vertical tube 11b2 connected to the D column hole, and a reinforced inclined tube 11b3 connecting the horizontal tube 11b1 and the vertical tube 11b2.

[0026] Please refer to Figures 2 and 3. In a preferred embodiment of the present application, a reinforcement strip 11b4 is provided on the inner and outer walls of the reinforced inclined tube 11b3. The reinforcement strip 11b4 and the horizontal tube 11b1 are connected by a reinforcement plate 11b5. The strength of the corner is increased by the reinforcement strip 11b4 and the reinforcement plate 11b5.

[0027] Please refer to FIG. 1 and FIG. 2 . In another preferred embodiment of the present application, the bottom center of the adhesive chamber 10 is convex upward to form a boss 103 , and the edge of the boss 103 is provided with a plurality of ribs 104 .

[0028] The other end of each rib 104 is connected to the inner wall of the glue cavity 101, and each glue outlet channel 102 is located between two adjacent ribs 104. The glue cavity 101 is divided into four equal parts by the boss 103 and the rib 104 to evenly distribute the glue in the glue cavity 101.

[0029] Specifically, the boss 103 is a conical structure, the height of the boss 103 is less than the depth of the glue chamber 101, and higher than the height of the rib 104. This arrangement can facilitate uniform distribution and mixing of the glue during high-speed centrifugation.

[0030] Please refer to Figures 1 to 3. In a preferred embodiment of the present application, an exhaust groove 111 is provided on the outer wall of the injection end of the injection tube 11. The exhaust groove 111 can facilitate timely discharge of air in the D-pillar hole during injection.

[0031] Furthermore, a positioning hole 105 is provided on the outer wall of the integrated housing 10 , and the integrated housing 10 is positioned through the positioning hole 105 .

[0032] In summary, in the present invention, since an integrated housing 10 is used, glue leakage will not occur, the glue outlet channel 102 can discharge glue evenly, and glue contamination on the product surface can be avoided, thereby improving product yield, increasing production efficiency, and reducing production costs.

[0033] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. The above-mentioned embodiments only express several implementation methods of the utility model, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
